Abstract:
This paper discusses the mechanism of microbial electrolysis cell coupled with anaerobic digestion (MEC-AD) system, which utilize microbial catalysis to generate methane under applied voltage. It analyzes the factors influencing methane production efficiency in MEC-AD, including applied voltage, electrode material, temperature, and pretreatment. The distribution of the main methanogenic microbial communities in MEC-AD system was analyzed, and the application effect of the MEC-AD system on anaerobic treatment of food waste and industrial wastewater to promote methane production was summarized. It concluded that further research is needed on electrode material configuration and cost-effectiveness. substrate pretreatment and actual application cost to provide a solid theoretical foundation for the engineering application of the system.
